Your baby's Social Security card shows up in the mail, and within a week somebody tells you to "open a 529." Maybe it's your sister. Maybe it's a coworker who opened one the day their kid got a number. You nod, and then you wonder how a 529 plan actually works, what it pays for, and what happens to the money if your kid decides college isn't for them.

Here's the plain version, with the 2026 rules from the Internal Revenue Service (IRS), two worked examples, and the exits most parents don't know they have.

The short answer: A 529 plan is a state-sponsored education savings account. You put in after-tax money and it's invested. Under IRS rules, withdrawals are federally tax-free when they pay qualified costs. Those include college, trade school, apprenticeships, up to $10,000 of student loans and, from 2026, up to $20,000 a year of kindergarten through 12th grade (K-12) costs. Other withdrawals owe tax plus 10% on the earnings.

Key takeaways

  • You own and control the account. There's no federal deduction going in, but the growth is federally tax-free when it's spent on school.
  • The 2026 list goes well past tuition: housing for half-time students, computers, K-12 tutoring and test fees, apprenticeships, licenses and student loans.
  • In our examples, a $10,000 deposit saves about $307 of Pennsylvania tax, and a non-qualified withdrawal is taxed only on its earnings.
  • If your child skips college, you can switch to a relative, use it for training, or move up to $35,000 into their Roth individual retirement account (IRA).
  • A parent-owned 529 counts as a parent asset on the 2026-27 FAFSA, and state tax breaks and protections differ from state to state.
  • The costliest mistakes: treating a deduction like a credit, waiting to start, and shortchanging your own emergency or retirement savings to fund it.

What is a 529 plan?

A 529 plan is a tax-advantaged account for education costs, named after Section 529 of the federal tax code. The IRS calls it a qualified tuition program (QTP) and describes it as "a plan operated by a state or educational institution" in its 529 plans questions and answers.

  • Two types. "There are two basic types: prepaid tuition plans and savings plans," the IRS says. A savings plan is invested, so its value moves with the markets. A prepaid plan buys tuition credits ahead of time. The colleges in it "are typically public, in-state institutions in the state that sponsors the plan," according to the Securities and Exchange Commission (SEC). This guide focuses on savings plans.
  • Two roles. The account owner, such as a parent or grandparent, decides when money comes out and who it's for. The beneficiary is the student. The owner can switch the beneficiary to another family member without owing income tax.
  • Why families bother. College costs real money. The College Board's Trends in College Pricing 2025 puts average 2025-26 sticker tuition and fees at $11,950 a year for in-state students at public four-year colleges. At private nonprofit four-year colleges, it's $45,000. By KAV's math, four years of in-state tuition comes to $47,800 at today's prices, before $13,900 a year for housing and food.

How a 529 plan works, step by step

A 529 works in five steps: you open it, fund it, invest it, let it grow, and spend it on qualified costs.

  1. Open an account. You pick a plan, list yourself as owner and your child as beneficiary. You aren't limited to your own state's plan, though your state's tax break may depend on which plan you use (more on that below).
  2. Put in after-tax money. The IRS is blunt: "Contributions to a 529 plan, however, are not deductible" on your federal return. Anyone can contribute, and IRS Publication 970 says "There are no income restrictions on the individual contributors." There's no fixed federal yearly limit, but contributions "can not exceed the amount necessary to provide for the qualified education expenses of the beneficiary."
  3. Mind the gift rules on big deposits. Money you put in counts as a gift to the child. For 2026 the annual gift exclusion stays at $19,000 per recipient, according to an IRS news release from Oct. 9, 2025. Give one child more than that in a year, counting birthday checks and other gifts, and gift-tax paperwork comes into play. The FAQ below covers the five-year shortcut.
  4. Choose the investments. Most savings plans offer age-based portfolios, which the SEC says "automatically shift funds into more conservative investments as the beneficiary gets closer to college age." Static portfolios keep the same mix. The SEC is just as clear about risk: "As with most investments, you can lose money in an education savings plan." Plans can also charge enrollment, maintenance, program management and asset management fees, and fees lower your returns.
  5. Let it grow, then withdraw for school. Growth isn't taxed as it builds. When money comes out, the plan sends Form 1099-Q, which splits the withdrawal into earnings and your own contributions. Publication 970 puts the rule simply: "No tax is due on a distribution from a QTP unless the amount distributed is greater than the beneficiary's adjusted qualified education expenses." In plain terms, take out no more than the year's qualified bills, in the same tax year you pay them, and keep the receipts.

What a 529 plan can pay for in 2026

A 529 pays for far more than tuition, and the list grew under the tax law signed July 4, 2025. Here's what counts, from Publication 970 and the statute itself, 26 U.S.C. 529.

College, graduate school and trade school

At colleges, universities and vocational schools that are eligible for federal student aid programs:

  • Tuition and fees, plus required books, supplies and equipment.
  • Computers and internet. The IRS includes "the cost of the purchase of any computer technology, related equipment and/or related services."
  • Housing and food (room and board), but only for students enrolled at least half-time.

K-12 school: up to $20,000 a year

Starting with 2026, up to $20,000 a year per student can go to K-12 costs at a public, private or religious school. That's double the old $10,000 cap, and the list now reaches well past tuition:

  • Curriculum materials, books and online educational materials.
  • Tutoring outside the home by a qualified tutor who isn't related to the student.
  • Fees for standardized tests, Advanced Placement (AP) exams and dual enrollment.
  • Educational therapies for students with disabilities.

Apprenticeships, credentials and licenses

Fees, books, supplies and equipment for an apprenticeship program registered with the U.S. Department of Labor qualify. Since July 2025, so do the costs of a recognized postsecondary credential program, the testing fees to earn or keep a credential, and continuing education that's required to keep one. The statute's list of credentials includes "any occupational or professional license issued or recognized by a State or the Federal Government."

Student loans

Up to $10,000 per person, over a lifetime, can repay the beneficiary's qualified student loans. Each brother or sister of the beneficiary has a separate $10,000 limit of their own.

What it doesn't cover

Anything outside those lists is a non-qualified withdrawal: a car, a phone bill, a spring-break trip, or housing for a student taking fewer than half-time classes.

Worked example: what the tax breaks are really worth

These two examples use round, illustrative numbers. The people aren't KAV clients, and the arithmetic is KAV's.

Rachel and Omar: a state deduction is worth hundreds, not thousands

Take Rachel and Omar, both 34, in Allentown, Pennsylvania, with a 3-year-old daughter. They put $10,000 into her 529 before December 31.

  • Federal deduction: $0.
  • Pennsylvania taxable income: $10,000 lower.
  • Pennsylvania tax saved at 3.07%, the rate in Pennsylvania's 2025 income tax instructions: about $307.

A deduction lowers the income you're taxed on, not the tax itself. It's a common mix-up on parenting forums, where people expect a $10,000 deposit to take $10,000 off the bill. The bigger prize is the tax-free growth. If the account grows by $15,000 over the years and all of it pays for college, none of that $15,000 is taxed federally.

Linda: pulling money out for something else

Take Linda, 52, a single mom in Ohio. Her son's 529 holds $40,000: $25,000 she put in and $15,000 of growth. She takes out $8,000 to help him buy a car, which isn't a qualified expense.

  • Share of the account that's earnings: $15,000 divided by $40,000, or 37.5%.
  • Earnings inside her $8,000 withdrawal: $3,000. The other $5,000 is her own money coming back, tax-free.
  • The $3,000 is taxed as income, federally and possibly by her state, plus a 10% additional tax: $300.

The 10% hits only the growth, not the whole withdrawal, and Form 1099-Q does the split for you. If her son had earned a tax-free scholarship, Publication 970 lets her withdraw up to the scholarship amount without the 10%, though the earnings would still be taxed.

What happens to a 529 if your kid doesn't go to college?

The money isn't lost. Kids take gap years, choose apprenticeships or skip college altogether, and a 529 has five exits.

  1. Switch the beneficiary. "There are no income tax consequences if the designated beneficiary of an account is changed to a member of the beneficiary's family," says Publication 970. Family is broad: siblings and step-siblings, parents, the beneficiary's own children, nieces and nephews, aunts and uncles, in-laws, first cousins, and the spouses of any of them. A younger sibling is the obvious candidate.
  2. Use it for training instead. Trade school, a registered apprenticeship or a licensing program can all qualify, as the list above shows.
  3. Move up to $35,000 into the child's Roth IRA. A Roth IRA grows tax-free for retirement. The rules are strict, so they're spelled out below.
  4. Use the scholarship or military academy exception. Withdrawals up to the amount of a tax-free scholarship, or up to the cost of attending a U.S. military academy, skip the 10% additional tax.
  5. Cash out. You'll owe income tax and the 10% on the earnings, as in Linda's example. Your own contributions come back tax-free.

The 529-to-Roth IRA rollover rules

Under the statute, a rollover to a Roth IRA only works if every one of these is true:

  • The 529 is old enough. It has been open for at least 15 years.
  • The money isn't new. Anything put in during the last five years, and the earnings on it, has to stay behind.
  • It moves directly. The money goes by direct transfer to a Roth IRA in the beneficiary's own name.
  • It fits the yearly limit. Each year's rollover counts toward the beneficiary's annual Roth IRA limit, minus anything else they put into IRAs that year. That limit is $7,500 for 2026, per an IRS news release from Nov. 13, 2025.
  • It stays under the lifetime cap. The total can't go over $35,000.

At the 2026 limit, moving the full $35,000 takes at least five years by KAV's math. That's four years at $7,500 ($30,000) and $5,000 in the fifth, assuming the beneficiary qualifies for the full limit. For how Roth accounts work, see our guide to Roth IRA vs traditional IRA.

Financial aid and state rules that change the math

Federal aid forms and your state's tax rules can matter as much as the federal tax break.

How a 529 counts on the FAFSA

On the 2026-27 Free Application for Federal Student Aid (FAFSA), 529 savings plans are reported as investments. The form says they "must be reported as an asset of the parent if the student is required to report parent information." Parents don't report 529s held for their other children, and a prepaid plan counts at its refund value.

Pennsylvania, as one example

KAV is based in Pennsylvania (PA), so here's how one state handles it. Other states differ.

  • Any state's plan earns the deduction. The PA-40 instructions say contributions to a Pennsylvania 529 account and to other 529 plans are deductible. You claim it on PA Schedule O.
  • The limit. For 2025, Schedule O allows up to $19,000 per beneficiary for each taxpayer. The PA 529 program says a married couple filing jointly can deduct $38,000 per beneficiary if each spouse had at least $19,000 of income.
  • What PA 529 adds. According to PA 529, money in its accounts is exempt from Pennsylvania inheritance tax, "protected from creditors in Pennsylvania," and not counted for Pennsylvania state financial aid. It adds that "Assets in out-of-state plans are not protected" and that other states' 529s do count for state aid.
  • K-12 follows the federal limit. PA 529 says qualified K-12 withdrawals up to $20,000 per beneficiary a year count for Pennsylvania tax purposes too.

Other states

The SEC says "Many states offer tax benefits for contributions to a 529 plan." The details vary: which plans qualify, how much counts, and whether K-12 costs and Roth rollovers get the federal treatment. The SEC also notes that a lower-cost out-of-state plan can come out ahead "even when taking tax incentives" for your home state's plan into account. Check your state's revenue department before you choose.

Common 529 mistakes parents make

Most of these come straight from the questions parents keep asking online.

  • Treating a deduction like a credit. Rachel and Omar's $10,000 deposit cut their Pennsylvania tax by about $307. Don't size deposits around a tax break you've overestimated.
  • Waiting until you can save "enough." If you're starting when your child is 10, it's easy to feel hopelessly behind. Growth needs time, so a small deposit made early can do more work than a bigger one made later. Our guide to how compound interest works shows why.
  • Shortchanging your own safety net. Your child can pay for school with scholarships, work and federal student loans. Your emergency fund and retirement have no such backup, so it usually makes sense to build an emergency fund first.
  • Assuming the money is trapped. It isn't, as the five exits above show. "What if they don't go?" is a reason to know the rules, not a reason to skip saving.
  • Ignoring fees and the investment mix. Fees lower returns, the SEC says, and a static portfolio won't get more conservative on its own as the first tuition bill gets closer.
  • Forgetting who keeps the deposits coming. A 529 grows only while someone funds it. If the parent making the monthly deposits died or couldn't work, the saving would stop. That's why a college goal belongs in the how much life insurance do I need math, next to the mortgage and the daily bills.

Where to start this week

  1. Look up your state's 529 plan and its tax rules, including whether a deduction or credit applies to other states' plans.
  2. Read the plan's disclosure documents for fees and investment options, and compare at least two plans.
  3. Pick a monthly amount you can automate, even a small one, and schedule it for the day after payday.
  4. Tell family how to contribute, so birthday and holiday money can go straight into the account.
  5. Start a receipts folder and plan to match each year's withdrawals to that year's qualified bills.
  6. If your child was born from 2025 through 2028, read our comparison of a Trump account vs a 529 plan before you decide where the first dollars go.
  7. Check that the plan holds up without your paycheck, using our financial checklist for new parents.

Frequently asked questions

What is the 5-year rule for 529 plans?

It means two different things. For gifts, the statute lets a giver spread one large deposit over five years of gift exclusions. In 2026, that means one person could put in up to $95,000 at once ($19,000 times five) and file a gift tax return. For Roth rollovers, money added to a 529 in the last five years can't be moved to a Roth IRA.

Can grandparents or other relatives put money into a 529?

Yes. Anyone can contribute, and there are no income limits on contributors. Each giver's total gifts to one child above $19,000 in 2026 bring gift-tax paperwork into play. In Pennsylvania, every taxpayer, grandparents included, can deduct up to $19,000 per beneficiary under the 2025 Schedule O, so a grandparent who contributes can claim their own deduction.

Can a 529 pay for a laptop?

For college, yes. The IRS counts "the cost of the purchase of any computer technology, related equipment and/or related services" as a qualified college expense. For K-12, the federal list covers curriculum, books and online educational materials, but it doesn't name computers. Check with your plan or a tax professional before using 529 money for a younger child's laptop.

Do you have to use your own state's 529 plan?

No. The SEC's investor bulletin compares in-state and out-of-state plans and notes that a lower-cost plan elsewhere can come out ahead even after your home state's tax break. Your state's rules still matter. Pennsylvania deducts contributions to any state's 529, but its creditor protection and state financial aid exclusion apply only to PA 529 accounts.

How much does $100 a month in a 529 grow to in 18 years?

You'd put in $21,600 over 216 months. At an assumed 6% a year, compounded monthly, the account would reach about $38,735 by KAV's math, with $17,135 of that from growth. At $500 a month it would reach about $193,677 on $108,000 of deposits. These are hypothetical, not forecasts; a 529 savings plan can lose money.
